NCP81119, NCP81119A Multiple-Phase Controller with SVID Interface for Desktop and Notebook CPU Applications The NCP81119/A Multi−Phase buck solution is optimized for http://onsemi.com Intel® VR12.5 compatible CPUs with user configurations of 4/3/2/1 phases. The controller combines true differential voltage sensing, differential inductor DCR current sensing, input voltage MARKING DIAGRAM feed−forward, and adaptive voltage positioning to provide accurately regulated power for both Desktop and Notebook applications. The 1 NCP 81119 control system is based on Dual−Edge pulse−width modulation (PWM) combined with DCR current sensing providing the fastest QFN32 CASE 510AT ALYWG G initial response to dynamic load events at reduced system cost.
